Unknown screw stuck to motor when changing.

It look long enough to be a gearbox shell screw 

Has this been opened before otlr worked on or is it brand new? 

 
Have you checked how many are in your gearbox shell?

It looks like one of the top row of screws.

I've only ever changed the hop and barrel never had the gearbox apart myself.

I'll split the gun and have a look see if it's the top row hopefully as never had gearbox fully out.

Had the gun 3 years but only recently took apart to change barrel and that so weird if it is gearbox screw.

Thanks

 
Have you had the motor out before? there's a chance it picked up the extra screw in the factory.

Chuck it in the box of bits and then at least you can find it if it turns out it has a home.

Nah first time for motor, once I've checked the gearbox and all there you could be right just picked up a spare as magnet.

All top screws I can see on the gearbox are there so assuming it's a spare that got picked up by the motor.

Never had the bottom half of the gearbox out. One day I will so will keep it in case its bottom set.

Cheers guys.

Keep it handy & if your barrel drops off... you'll know where it came from.

 
There is a short screw(ooh matron)in the lower half of the gearbox just to the right of the trigger. It could possibly be that one.

Thanks, if the lower half means taking it further apart than above?

I'll have a gander to see if I can see anything from externally

Ahh thought so haha! I'll leave it for now and see when I come to look in the gearbox. Never had issues test firing the gun for chrono and going to take it for a run out on Sunday so will see. Thanks for the help

So if the screw comes from the gearbox, how would it have got into his handgrip if he's never taken the motor out before?

I'm thinking that maybe someone before him has had a tinker.

 
To me, it looks like a baseplate screw from the pistol grip. Every chance it got in there in the factory.
Aren't the pistol grip screws the one I posted as a picture in the original post or is there other screws?

Gun fires fine and everything so hopefully won't fall to bits haha

I mean the ones you took out to get the bottom of the pistol grip off, to be able to remove the motor.

Didn't have to remove any screws to get the motor out on my specna, so unsure what you mean.

My specna just has a push grip kind of lock on my bottom that holds the motor there, unless some have a screwed bottom plate?

See below a screenshot from dissembly video, just a push to lungs to open it up, under there is just a plastic thing where you can do the motor height
